For my treatment in Truk/Honolulu 2008, DAN reimbursed the foreign health care provider Australian Hyperbaric Health (Truk Recompression Chamber); while for the Honolulu follow-up treatment, my primary insurance from work covered all expenses. (DAN also provided for the hotel on Waikiki Beach as I was recovering from my Honolulu Follow-up).
It took a year of email/snail mail correspondence between myself, DAN and their insurance underwriters and Hyperbaric Health Australia before I was finally cut a check from DAN which was then bank wired to Australia. My primary health care insurance from work immediately covered all the expenses from Honolulu (Kuakini Medical Center, Hyperbaric Medicine & Ultrasound Dept, and Queen's Hospital Emergency /CT Radiology Dept) within a month -probably because the services were rendered in the US. . .
